“Musicians and engaged couple Kacey Musgraves and Ruston Kelly took the stage at Tennessee’s idyllic Blackberry Farm recently, performing a sweetly pastoral new tune they wrote, with lyrics based on a 1970 poem penned by Johnny Cash to June Carter Cash. “To June, This Morning” offers a husband’s reflections of the couple’s routine as they wake to face the day at home, a quiet portrait in stark contrast to the globetrotting lives they experienced simultaneously as two of the most in-demand entertainers at the time.”
